SPRING-BEARING FOR CREAM-SEPARATORS.

SPECIFICATION forming part of Letters Patent No. 792,980, dated June 20, 1905.

Application filed June 29, 1904- erial No. 214,603.

separators, and has for its object to provide a simple but durable and effective spring-bearing for cream-separators which will allow for accurate adjustment and easy repairing at any time the bearing becomes out of order.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which Figure 1 is a plan view of my improved bearing, a portion of the casing and plate being broken away to show one of the plungers in full lines; Fig. 2, a section on the line 2 2 of Fig. 1; Fig. 3, a bottom plan view of the adjusting-plate.

A represents the casing of the hearing, which is held securely by a driving fit into the casing of the machine.

B is a central opening formed vertically through the casing A, slightly larger than the spindle of the bowl.

C represents plungers fitted within openings formed radially through the casing A, and the inner ends of these plungers extend through into the opening B and are concaved to form a bearing for the spindle. D represents springs interposed between the outer end of said plungers and a screw plug E threaded into the casing. The tendency of these springs is always to press the plungers toward the spindle.

F is a circular plate fitted within a circular opening in the top of the casing, and this plate F has a central opening F slightly larger than the opening B through the casing.

G represents concentric slots formed through the plate F, and H represents setscrews passing through said slots into the easing, so that by loosening the set-screws H the plate may be turned. Extending downward from said plate is the spirally-formed cam I. Each of the plungers C has formed therewith the shoulder C, which shoulder is forced against the cam I by means of the springs D. Thus by turning the plate F in one direction the plungers may be forced outward by the cam I, and by turning the plate in the opposite direction the cam will allow the springs to force the plungers farther inward.

Cream-separators are designed to be run at a large number of revolutions per minute, and when they attain their full number of revolutions the spindle is balanced in the center of the bearing; but when the separator starts and the revolutions are increasing the bowl is liable to run out of true, and therefore it is necessary to have a yielding bearing to accommodate it. This is the purpose of my improved spring-bearing, and by means of the cam I, I am enabled to regulate the size of the bearing accurately. The edge of the plate F may be graduated, as represented at J, and a pointer J may be marked upon the upper surface of the casing A.

Of courseI do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is- 1. In a spring-bearing for cream-separators, a casing having a central opening formed therethrough, said casing provided with radial horizontal openings formed therethrough, plungers adapted to slide within said openings, the inner ends of said plungers extending through into the inner opening of the casing and being concaved so as to form a bearing for the spindle, springs adapted to force said plungers inward, a circular plate, said plate provided with a spirally-formed cam upon its lower surface, the plungers provided with shoulders abutting against said cam, the circular plate adapted to be revolved to different positions, and means for holding said plate in any position adjusted, as and for the purpose specified.

2. In a spring-bearing for cream-separators, a casing provided with a central opening formed therethrough, said casing provided with radial openings formed horizontally therethrough, plungers adapted to slide within said openings, the inner ends of said plungers extending through into the inner opening of the casing and being concaved to form a bearing for the spindle of the bowl, springs tending to force said plungers inward, a circular plate guided within a circular recess in the casing, said plate provided with a spiral cam upon its under surface, the plungers provided with shoulders upon their upper surface abutting against said cam, the circular' plate provided with a central opening, said plate also provided with concentric slots formed through the same near its periphery, set-screws passing downward through said slots into the casing, as and for the purpose specified.

3. In a spring-bearing for cream-separators, a casing having a central vertical opening formed therethrough slightly larger than the spindle of the bowl, said casing provided with radial horizontal openings formed therethrough, plungers adapted to slide within said openings, the inner ends of said plungers extending through into the central opening of the casing and being concaved to form a bearing for the spindle of the bowl, plugs screwed into the casing at the outer end of the radial openings, springs interposed between the outer end of the plungers and said plugs, a circular plate journaled in a circular recess formed concentric with the central opening of the casing, said plate provided with a central circular opening slightly larger than the opening through the casing, said plate provided upon its under side with a spiral cam, the plungers provided with shoulders upon their upper side abutting against the cam, said circular plate also provided with concentric slots formed through the same near its periphery, and set-screws extending through said slots into the casing, as specified.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

HARRY B. GARMAN.
